GAGE-COCK.

SPECIFICATION forming part of Letters Patent No. 263,018, dated August 22, 1882.

Application filed May 22, 1882. (No model.)

To'all whom it may concern:

Be it known that I, J ESSE M.BB.OWN, ofBoston, in the county of Suffolk, State of Massachusetts, haveinvented a certain new and useful Improvement in Gage-Cocks, of which the followingis a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forminga part of this specification, in which-s Figure l is a vertical longitudinal section, and Fig. 2 a view of the handle.

Like letters of reference indicate correspondingpartsinthedifferentfiguresofthe drawings.

My invention relates to that class of gagecocks which are used with'steam-hoilers; and it consists in a novel construction and arrangement of parts, as hereinafter more fully set forth and claimed, by which a simpler, cheaper, and more effective device of this character is produced than is now in ordinary use.

In the drawings, A represents the body of the cock, which is provided with the globular enlargement B, inlet O, and discharge-nozzle D.

Between the inlet chamber O and globular chamber B there is a diaphragm, E, through which there is a small opening, a, connecting the two chambers.

Mounted on the valve-stem G there is a conical valve, H, provided with an opening, m, corresponding with the opening a, and fitted nicely to the valve-seat x00, formedin the body A and diaphragm E.

The stem G is provided with an annular projectiomz, which is fitted to work closely in the body A, the outer end of which has a section cut away, as seen at n, to form a stop for the pin 1). The valve-stem and valve are held in position by the cap-nut J, through which the stem passes, and on the outer end of which there is a weighted handle, K.

In the use of my improvement, the dischargenozzle D being downward, ifit is desired to close the cook the handle K is turned into a horizontal position, or so that the hole min the valve does not register with the hole a in the diaphragm E, as shown in Fig. 1, the weighted handle acting by gravitation to keep To open the valve the handle is raised to a vertical position, bringing the pin b against the opposite shoulder of the stop it, and cansing the holes a m to register, thus permitting the steam or water to pass from the chamber 0 through the valve H into the chamber B,

and thence out through the discharge-nozzle D, in a manner which will be readily understood by allconversant with such matters without a more explicit description.

In ordinary gage-cocks of this character there is no hole in the valve H, and the stem G is provided with a wheel, instead of the handle K, and with an exterior or male screwthread near its outer end, the hole through which the stem passes in the nut J beingcorrespondingly threaded, so that when the wheel is turned to the right or left the valve H will be raised or lowered and the valve opened or closed accordingly; but where the stem and cap are so connected the stem is liable to wear and work loose in the cap, rendering the cock liable to open accidentally or to leak-an objection which is entirely obviated by my improvement.

Having thus explained myinve-ntion, what I claim is- A gage-cock consisting of a straight tubular body screw-threaded at both ends and comprising an inlet-chamber and a globular chamber, with a perforated diaphragm between said chambers, a discharge-nozzle connected to the globular chamber, a screw-threaded cap at the outer'end of the body, a conical perforated valve adapted to fit the diaphragn1,a horizontal valve-stem arranged centrally in the body of the cock and in line therewith, said valvestem being provided with a collar adapted to fit the outer end of the body, said collar hav ing a stop-pin which works in a slot in the outer end of the body, and a handle for operating said valve-stem and valve, all constructed, combined, and arranged to operate substantially as described.
